Wealth Elasticity, Agent Heterogeneity and Fiscal Dynamics

The literature on fiscal policy has identified wealth elasticity of labor supply and agent heterogeneity as the linchpin of shaping different transmission mechanisms for fiscal policy. In this paper, I build these two important edifices on an otherwise canonical business-cycle model to conduct quantitative analyses of various fiscal policies. To underscore the relative importance of agent heterogeneity, I compare results from the model with agent heterogeneity with those from a standard model without agent heterogeneity. I also compare results from changes in wealth elasticity to analyze how the model ingredient delivers different macroeconomic and fiscal dynamics. The main finding reveals that in the context of the model formulated in this paper, the capital tax is the least detrimental to business cycles and fiscal states and the consumption tax is the most appropriate policy tool since it yields positive output and tax-revenue multipliers in the short and long runs. All the results from counterfactual experiments suggest that macroeconomic and fiscal outcomes hinge fundamentally on agent heterogeneity and wealth elasticity. An important value that this paper adds to the literature is to offer results from a comprehensive analysis of all possible fiscal policies by considering both essential forces.
